In November 2025, Tuoxinda (Qidong) Pharmaceutical Biotechnology Co., Ltd. (hereinafter referred to as "Tuoxinda") undertook a high difficulty organic silicone oil emulsification project. At the beginning of the project, a screw pump was used for feeding, but due to the lack of corrosion resistance and inaccurate feeding of the screw pump, as well as the high viscosity of the material, there were difficulties in feeding, dispersion, and parameter control, resulting in significant differences between batches and frequent scrapping of unqualified batches, causing significant losses. Later, we switched to using a refined three plunger pump for feeding, and multiple batches of products showed no inter batch differences, successfully achieving continuous and stable emulsification. The customer was very satisfied.

Objective of the experiment

Continuous emulsification of organic silicone oil

Conveying materials

Organic silicone oil containing organic solvents

1. Improve the three plunger pump

2. Customer provided specialized emulsification equipment

Experimental Procedure

1. In response to the problems of corrosion resistance and inaccurate feeding of the original screw pump, an improved three plunger pump is adopted;

2.Build a continuous emulsification system and conduct multiple batches of experiments.

Multiple batches of products have met customer satisfaction without any inter batch differences, successfully achieving continuous and stable emulsification.

The customer's thank-you letter states thatThank you to Jingjin Three plunger Pump for helping me solve the feeding problem and complete the high difficulty emulsification project. Thank you to Jingjin team for their tireless efforts and responsive after-sales service!Improving the three plunger pump is helping meconstantlyBreaking through technological bottlenecks,implementContinuous flow developmentof利器。The refined three plunger pump is worth recommending to colleagues who work on continuous emulsification projects! ”
